got HIDs/Xenons (Raylux, 35W, color temp 6000K) fitted with ballasts. seems to be quite strong lighting, much better than the stock halogens. Could not get hold of any projector lamps for SX4, else would have searched for 4300K ones which are still brighter (used as OEM in mercs and beemers).
the person who installed in my city is an HID specialist - when asked for 4300K ones, told me that its too bright and without projectors can confuse oncoming traffic, hence is not sold as such.

Does have any contact details of big shots in Maruti Customer care (Northern region). My colleague has been facing continuous problems with his SX4, now the dealer damaged one of his cars bumper and refuses to repair the same.
Help needed .

Guys, round beam lights are the best. They spread wider & deeper .
Get a white hella rally 1000,firmly fix it to the bumper( make sure clamping is done to the chassis under the bumper). Get the relay fixed by good electrician ask him to connect it to high beam. So that extra light will not work in low beam. Now night driving will be a pleasure

Alternative/Auxillary Hella lighting is best, you save your OEM reflector, wiring, and bulb and get warranty. Stock upgrade Hi-Fi 60/55s are useless as they fuse early and you may be left with only high/low beam.

I wonder why Maruti has left such a car with a single bulb, 2 beam HL.

Would this be captured as an error code? Can I ask the service person to check that?

Will have to check on that. If your SA is a good man he will take the trouble to check it out. Most are too hard pressed to spend their time checking out and understanding rare error codes. Not their fault too.

I have observed this during a missed crank. Definitely didn't face an issue when restarting in traffic but sometimes the car doesn't start in one crank. This is something to do with the throttle body which doesn't let the engine idle correctly after a stall.

Since the car is drive by wire, the engine idle is controlled by the throttle motor itself and there is no separate Idle air control valve unlike cars with mechanical throttle. Suppose the car stalls, the ECU slightly opens up the throttle for the next start and hence you will observe that the engine roars up to 2K rpm and later settles down to idle. Sometimes this doesn't happen and that is when the car doesn't start. Once the cranking is unsuccessful, the throttle motor is again commanded to open up and this time the car will start successfully.

Suppose the car stalls, immediately turn the key to ACC position before you start it. This will recalibrate the throttle motor and give you a successful start.

Once in a while, before start, perform throttle body recalibration. Do this by moving the key to ON position, pressing accelerator pedal all the way down and keeping it there, switch off ie, move the key back to off position. You can hear the motor calibrating itself once you turn the car ON the next time.

Wow!! this works. There is a noticeable difference in acceleration. Lets see how it goes.
I don't know if this will solve the stalling problem. There is no way i can reproduce it effectively. Only time will tell.

First problem have been solved, but to my surprise, in ZXi version it is not possible to just change bearings, they had to change whole hub costing 7700, under warranty. God knows how will manage after warranty. I hope all these are covered under extended warranty.

I checked in the service manual. In the rear, it is a hub, unlike the separate bearing in the front. How much did your wheel bearings last?

They lasted more than 75K. They hadn't given out actually. The bolt of the tyre had got jammed, and had to be welded out. A lot of pulling and tugging somehow damaged it a bit. The guy told me its good for another few thousand kms. But i was gonna take a trip the next week. So just got them changed as a precaution.
